Abstract
The utility model relates to a kind of low nitrogen vapor boilers of combustion gas, including smoke chamber, inner ring heat exchanger tube, corrugated plating and the outer ring heat exchanger tube being successively socketed from inside to outside, the side of inner ring heat exchanger tube offers the second outlet flue, cloth cigarette sleeve is socketed between smoke chamber and inner ring heat exchanger tube, the first outlet flue relative to radial deflection is offered on cloth cigarette sleeve, first outlet flue is connected to the second outlet flue through the annular space between cloth cigarette sleeve and inner ring heat exchanger tube, and the first outlet flue is located at the downstream adjacent position that its deflection spins up the second outlet flue.Using cloth cigarette sleeve is arranged in smoke chamber, the first outlet flue on cloth cigarette sleeve can guarantee that flue gas, along spiral path migration, maximizes the sinking path of flue gas in inner ring heat exchanger tube, improve radiating efficiency.
Description
Technical field
The utility model belongs to field of boilers more particularly to a kind of low nitrogen vapor boiler of combustion gas.
Background technique
Boiler is a kind of energy conversion, and the energy inputted to boiler has chemical energy, electric energy, high-temperature flue gas in fuel
The forms such as thermal energy, and pass through boiler and convert, output outward has steam, high-temperature water or the organic heat carrier of certain thermal energy, and
Boiler of today all advocates energy conservation and environmental protection, and traditional steam boiler rate of heat exchange is low, causes energy loss larger, and vertical through-flow steams
Boiler furnace steam flue gas at washing away up and down, this is washed away, and mode flue gas flow rate is low, and heat exchange efficiency is low, in addition causes product manufacturing size
Greatly, it takes up a large area.Occur a kind of low nitrogen vapor boiler of the combustion gas for encircling type heat exchange process using ω type flue gas on existing market,
Flue gas can be improved in the erosive velocity of vertical automatic steam boiler heat exchanger tube in the boiler, improves heat exchange efficiency.
But limited by the distributing position of outlet flue, the flue gas close to outlet flue position can directly be discharged from outlet flue, nothing
Method and heat exchanger tube complete heat exchange, lead to thermal loss, reduce heat exchange efficiency.
Utility model content
The purpose of this utility model is to provide a kind of low nitrogen vapor boilers of combustion gas that heat exchange efficiency is high, and technical solution is such as
Under:
The low nitrogen vapor boiler of combustion gas, smoke chamber, inner ring heat exchanger tube, corrugated plating and outer ring including being successively socketed from inside to outside change
Heat pipe, the side of inner ring heat exchanger tube offer the second outlet flue, and cloth cigarette sleeve, cloth cigarette are socketed between smoke chamber and inner ring heat exchanger tube
The first outlet flue relative to radial deflection is offered on sleeve, the first outlet flue is through between cloth cigarette sleeve and inner ring heat exchanger tube
Annular space is connected to the second outlet flue, and the first outlet flue is located at the downstream adjacent position that its deflection spins up the second outlet flue.It utilizes
Cloth cigarette sleeve is set in smoke chamber, and the first outlet flue on cloth cigarette sleeve can guarantee flue gas in inner ring heat exchanger tube along spiral path
Migration maximizes the sinking path of flue gas, improves radiating efficiency.
Further, inner ring heat exchanger tube is the spiral shape that the number of turns is greater than 1, the rotation direction of inner ring heat exchanger tube and the first outlet flue
Deflection rotation direction is in the same direction.
Detailed description of the invention
It, below will be to use required in embodiment in order to illustrate more clearly of the technical solution of the utility model embodiment
Attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the embodiments of the present invention, for this
For the those of ordinary skill of field, without any creative labor, it can also be obtained according to these attached drawings other
Attached drawing；
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
In order to keep the technical purpose, technical scheme and beneficial effects of the utility model clearer, with reference to the accompanying drawing and
Specific embodiment is further illustrated the technical solution of the utility model.
Referring to Fig. 1, the structural schematic diagram of the low nitrogen vapor boiler of combustion gas in the utility model is shown, mainly gives and changes
The sectional view of heat pipe arrangement.Specific structure is as follows:
The low nitrogen vapor boiler of combustion gas includes the smoke chamber 1 being successively socketed from inside to outside, inner ring heat exchanger tube 2, corrugated plating 3 and outer ring
Heat exchanger tube 4, the side of inner ring heat exchanger tube 2 offer the second outlet flue 5, and cloth cigarette set is socketed between smoke chamber 1 and inner ring heat exchanger tube 2
Cylinder 6 offers the first outlet flue 7 relative to radial deflection on cloth cigarette sleeve 6, and the first outlet flue 7 is through cloth cigarette sleeve 6 and inner ring
Annular space between heat exchanger tube 2 is connected to the second outlet flue 5, and the first outlet flue 7 is located at the downstream that its deflection spins up the second outlet flue 5
Adjacent position.Inner ring heat exchanger tube 2 is the spiral shape that the number of turns is 1.2, and the rotation direction of inner ring heat exchanger tube 2 is inclined with the first outlet flue 7
Oblique rotation direction is in the same direction.
Deflection is arranged first outlet flue 7 in the counterclockwise direction, and the density of the first outlet flue 7 is along far from the second outlet flue
5 direction is gradually reduced.The arrangement density of inner ring heat exchanger tube 2 is uniformly distributed on spiral path, can also be along far from the second outlet flue 5
Direction it is gradually sparse.
It should be noted last that: the technical solution of the utility model that the above embodiments are only illustrative and not limiting is appointed
What to the utility model carry out equivalent replacement and do not depart from the spirit and scope of the utility model modification or part replace,
It should cover within the scope of the utility model claims protection.
